Unmounted the large capacitor. It sparked when shorted. Unmounted the big diode—it looked OK. Unmounted the big resistor—it tested OK. Not trivial. Next checks are the voltage regulator. I pulled the board to take it home.

Worked on Ian's old Meade LX 200. Power supply blew its fuse. Jumpered it. Power was reaching the mount. But it instantly blew the onboard fuse.
